更改ReentrantLock的所有者(Changing owner for ReentrantLock)

 所以我写了一个小程序，它会绕着它移动，当它们碰撞时它们会向相反的方向移动，但是当我试图延迟执行时，它们不会在愚蠢的时候快速移动我得到java.lang.IllegalMonitorStateException在canvasRender中锁定.java，创建一个实例： 
 
ReentrantLock renderLock = new ReentrantLock();
 
 方法暂停执行一段时间，所以圈子不会超快移动。 
 
 publlic void delay(){    
        renderLock.unlock();
        try { Thread.sleep(10); } catch (Exception e) {} ;
        renderLock.lock();
    }
 
 然后从另一个类中创建一个窗口并添加actionListener 
 
public static void main(String[] args){
//Buttons and other elements
// ...
JButton start = new JButton("Start!");
createAndShowGUI();
}
 
 在createAndShowGUI（）中： 
 
static void createAndShowGUI(){
//adding elements to panels    
start.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent e) {
        start(); //this will set gameIsRunning variable to true and create models
        while (gameIsRunning) {
            //update(); //which has delay(); at the end of frame drawing
            //but even if just put delay()
            delay(); //still says exception
            start.setEnabled(false); //while game is running button is unavailable
            }
            start.setEnabled(true);
   }
});
}
 
 在这种情况下，我的锁被Thread main所拥有，但当我点击按钮“Start！”时 当前是Thread AWT-EventQueue-0 ，所以程序崩溃。 如何解决这个问题？ （或我在哪里愚蠢？） 

So I wrote a little program which will move circles around and when they collide they will move opposite direction, however when I'm trying to delay the execution so they won't move around stupidly fast I get java.lang.IllegalMonitorStateException Lock in canvasRender.java, creating an instance:
 
ReentrantLock renderLock = new ReentrantLock();
 
Method which will pause execution for a moment, so circles won't move around super fast.
 
 publlic void delay(){    
        renderLock.unlock();
        try { Thread.sleep(10); } catch (Exception e) {} ;
        renderLock.lock();
    }
 
then from another class where I create a window and add actionListener
 
public static void main(String[] args){
//Buttons and other elements
// ...
JButton start = new JButton("Start!");
createAndShowGUI();
}
 
In createAndShowGUI():
 
static void createAndShowGUI(){
//adding elements to panels    
start.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent e) {
        start(); //this will set gameIsRunning variable to true and create models
        while (gameIsRunning) {
            //update(); //which has delay(); at the end of frame drawing
            //but even if just put delay()
            delay(); //still says exception
            start.setEnabled(false); //while game is running button is unavailable
            }
            start.setEnabled(true);
   }
});
}
 
In this case my lock is owned by the Thread main, but at the time when I click button 'Start!' current is Thread AWT-EventQueue-0, and so the program crashes. How to fix this issue? (or where am I silly?)
